Arizona Diamondbacks right-handed pitchers Luke Weaver (elbow) and Keynan Middleton (elbow) are both scheduled to make rehab outings at Triple-A Reno on Thursday. Both players are on the injured list with right elbow inflammation. Weaver, who has been out since Opening Day, is expected to throw around three innings or 45 pitches on Thursday. Middleton, meanwhile, will only pitch an inning on Thursday. He's been on the shelf since mid-May.
